Thing is that Merkel’s Christian Democratic party needs more than 100 extra seats to form a majority that will allow it to govern. The Social Democrats are likely to stay out of a rulling coalition for the next few years. The AfD neo Nazis are out of discussion. The Left party won’t cooperate with anyone but the Social Democrats. In conclusion Angela Merkel needs to balance a coalition with her Christian Democrats, the business and markets focused Free Democratic party and the environmentally focused Green party. Good luck with that.
